The RowHeaderWidth and RecordWidth properties specify the widths of row headers and records respectively, in either absolute values (pixels) or relative values.
Absolute values are used when:
Relative values are used when row headers and the current record are stretched to fit the control's width. This happens in the following cases:
In these latter modes, each of the RowHeaderWidth and RecordWidth properties can be set to a value in the range [15;185]. The other property's value is calculated by subtracting this value from 200. So, the sum of the properties is always equal to the constant value of 200.
The absolute widths will be proportional to the specified relative values.
In addition, resizing the control horizontally in these modes modifies the width of row headers accordingly. To prevent row headers from being resized, set the BaseOptionsView.FixRowHeaderPanelWidth property to true.
Changing the RowHeaderWidth property's value raises the RowHeaderWidthChanged event.
